LIQUID nrsrnnsnnl Application filed December It, 1926. Serial No. 154,682.;

after a coin of any certain value has been. deposited in the apparatus, and to'provide means whereby the, size and value of thecoin will control the extent to which the pump may be operated. In this manner a definite relation is always maintained between the value of the coin and the volume of gasoline dispensed. I

A further object of the invention is to provide simple adjustable means for enabling the ext'entto which the pump'may be operate'd after the insertion of any certain coin, to be readily altered, so as to allow for any fluctuation in the price or lower value of the product,,and thus insure that the user will obtain just the right quantity of gasoline for his money at all times regardless of any changein unit price of the fuel.

The apparatus may be operated by any person without experience and may therefore be installed inany location, to take the place of an attendant to dispense the fuel, or as an auxiliary pump in a manually operated pump station,to be used by any individual I,

one end a'clutch; element 8-normallyengagmotorist when the station is closed and the attendant is absent, and thefmanually oper-- ated umps are disconnected or locked up. A urther object'of the invention is to produce a relatively simple and inexpensive device and yet one which willbe eXceedinglyeffective for'the purpose for which it is designed;

These objects we accomplish by means of such structure and relative arrangement o parts as will fully appear by a, perusal of the following specification and claims. v p

structure.

Fig. 5 is a top plan view of the initial Fig. 9 is a sectional elevation of a clutch "Referring now more particularly to the characters of reference on the drawings,-the numeral 1 denotes the barrel of an ordinary vertical gasoline pump, whose pistonrod 2 is connectedto a vertical rack 3. Adjacent the top .ofthe rack when the latter isinits ilowermost positionfis a support 4; turnably mounted on which is; a horizontal shaft :5.

Turnably mounted .on the shaft is a pinion 6 constantly meshing with the rack. :Slidably splined on the shaft is'a sleeve Tha-ving at in 'acoo erating elut'ch element 8 on the" p t. I pinion. For reasons hereinafteriset forth,

thejj'cluteh features ofelement 8. comprise pressed pins v8? limited in theirloutwa d movement,and' normally "seated i'nsocketsv 8 in'the element 8 as shown in Fig. A ratchet wheel 9 on the sleeve engages a pawl 10 mounted on the supf 1 port l,qand.prevents rotation of the shaft '5 and connected partsexceptin one direction; A 'yieldable lock or catch structure 11 between the sleeve and shaft serves to hold the sleevein either its clutch engaging or-disengag ng positions.

Thesleeve 7 is engaged by a shiftingfork '12 mounted on the support 4, the fork having a horizontal arm 18mountedfinconnection therewith .Theouter-endof the arm s .en- I paged by a grooved collar 14 which is mounted on a rotatable and-longitudinally movable ro.d};15 disposed adjacent and parallel togthe rack. This rod has a plurality of vertically spaced and oircumferentially. offset stop members 16 projecting radially therefrom, any one at a time of said stop members being setto facethe rack by means of a control structure hereinafter described. Such stop member will then he in position to be engaged by a fixed stop 17 projecting laterally from the rack after the latter has moved upwardly a certain distance. Upon the engagement of thestop 16 by the stop 17, the rod 15 and collar 14 are raised, which operates the shitting fork to cause the sleeve 7 to be retracted and the clutch elements between the sleeve and pinion to be disengaged.

The pinion is then free of the shaft, and a further rotation of the shaft will not effect a further rotation of the pinion or an upward movement of the rack. It will of course be evident that if a lower stop 16 is engaged by the'stop 17 the rack will lift a lesser distance, before the clutch is thrown out, than if an upper stop is engaged, and consequently a lesser amount of gasoline will be dispensed from the pump. The pinion being free of the shaft the rack is then free to return to its lowermost and normal position, either of its the element 8.

tionship with the pinion, ready for anotherdispensing operation. The yieldahle clutch pins 8 enables the downward movement of the-rod 15, and the consequent shifting of the sleeve 7 to take place when'the stop 17 engages the stop 19 with the downward movement of therack even ifthe pins are not at first lined up with their respective sockets in A yield-able lock structure 20 is arranged between the rod 15 and one "of its bearing members 21 to hold it in either its upper or lower position.

- The shaft '5 projects through a preferably cylindrical casing 22 which is disposed beyond the sleeve 7, the corresponding end of the shaft having a crank handle 23 thereon, whereby'the shaft may be readily turned.

:Keyed onto the shaft insi'dethe casingis a sleeve 24- having adjacent one end a plurality of circumferentially spaced sockets 25. A vertical p1n26 shdable m a bearing 27 in the casing below the sleeve, normally engages the lowermost socket, being held in such engagement by a spring 28; these parts forming a latch structure normally preventing the rotation of the member 24: and consequently of the shaft 5. The lower end of this pin is pivoted on a horizontal arm 29 pivoted in the casing, the arm being connected to a vertical.

rod 30 which extends upwardly to a connec- 29 to-move the pin 26 clear of the socket, by

means of'a horizontal lever 32 pivoted with a transverse axis onto a central shaft 33 turnably mounted in the casing. This lever, while freely rotatable with the shaft, cannot, however, be depressed until a coin of proper size'and value is inserted in any one of the different sized coin openings 3 1 provided in the casing for that purpose. Theparticular coin control mechanism we employ is de scribed later. 7 It will be seen,however, that until such coin is deposited, the pin 26 will remain engaged with the socket 25, and the crank-handle 23 cannot be rotated to turn the shaft and pinion and raise the rack. I

Slidable on the sleeve2is an outer sleeve 35, constantly pressed toward the pin 26 by a spring 36. This spring is mounted on a rod 37 which at one end is attached to the fork 12 and at theother-end is slidable through a bearing 38 fixed in the casing This spring is disposed between.saidbearing and a lug 39 depending from the sleeve 35,

and is also slidable on the rod 37,'thereby preventing rotation of the sleeve. By means of th1s arrangement it will be seen that as soon as the pin.28 is depressed clear of a socket 25, the sleeve 35 will move to cover the socket, preventing return of the pin to an engaged position with said socket, and permitting the crank-handle andconnected parts to be rotated to cause the rack LtO be lifted and gasoline dispensed from the pump. 3 The lug 39 then abuts against a stop'in the rod 37. Then when the shiftingfork is moved to a clutchdisengaging position, as previously described, the stop lO will press against and move the lug 3911) its original position, so that it will clear the socket and allow the pinto again move up into engagement withwhatever socket in the sleeve 24 is then alined with the pin. The shaft 5 and the corresponding handle are then again locked from rotation and can only be freed upon the insertion of another coin to enable the rod 30 to be againv depressed to release the pin 26. v

The lever 32 is free to turn with the-coir t-ral shaft 33 at any time, through a circumferential slot 411 inthe casing, so as to valine said lever with any one of the vertical slots 1 11 in the casing provided above the corresponding coin openings 3ta nd communi eat ng with the slot 41.

15 to be positioned relative to the Step1? on the rack so that the latter can r se to an exthe form of adjustable nuts 4L0 mounted on Y This movement causes the corresponding stop 16 on the rod i of are rollers 46, mounted on pivoted arms tent which depends on the value ofthe coin deposited in the corresponding coin opening." This is accomplished by means of radial and parallel arms'42 fixed on the shaft 33 and rod 15, which arms are coupled by a link 43. I

The circumferential spacing of the stops 16 is, the same as the circumferential spacing of the slots 41 in the casing, so that the proper.

one of said stops will be lined up with the stop 17 when the lever 82 is linedup with a.

corresponding slot 41. The rod 15 is suitably graduated for practically its entire length, in any suitable units'of measurement, so that the stops can be easily and accurately adjusted on the rod to different longitudinal positions asthe priceof the gasoline fluctuates. o v 1 Any suitable coin control mechanism may.

be used for controlling the depression of the lever 32. We preferably provide a mechanism for the purpose constructed asfollowsz Leading downwardly from each coin opening 34 is a vertical coin chute 44, just the sufii cient width to readily allow a coin of cer tain diameter to drop therethrough while being maintained-in a vertical position. Proecting into thechute on opposite sides there- 46, the rollers normally preventing the coin from dropping past. A light spring S between the arms tends to hold the rollers inwardlyof the chute. Thearm of one roller has an extension arm 47 projecting above the roller and formed rigid with thearin46.

The upperand free end ofthe arm 47 en- A gages a horizontal bar 48 pivoted in thecas mg on'a vertical axis. A spring 49- acts'to pressthe bar. against the arm, andImaintain the latter so that theroller 46 projects inwardly of the chute. The bar when in that position forms a'stop for a'horizontal lug -50 projecting radially from averticalrod fil mounted in thecasiiig and arranged for limited vertical movement, said rod-being nor} mally pressed upwardly by a spring 52 (see Fig. 1). 'Theupper endofthis-rod. terminate's directly under the lever 32fwhen the latter is alined with-the corresponding slot 41. 'Pivoted in connection with one SldGI'Of the chute 44 isa presser member 53 whose free end is adapted to pro ect into the chute andwhen turned on its pivot to bear down on a coin in-the chute which is at that time held from further descent by the stop rollers v of the coin.chute.- The otherend of this bellcrank "s adapted to engageahorizoiital stop pin 57 mounted for.movementacross-theslot 41, and so positioned as topas's above the lever when the latter iszdepressed in the slot. The pin is normally held retracted from the slot by a spring 58.

In operation it is assumed in this case that rollers-'46, and that another coin lying in superimposed relation on the first coin is necessary to cause the device to operate. This could be avoided if desired, however, by

lowering the presser relative to the stop roller. The initial depression of the lever in a coin is alwaysin the chute, stopped by the the slot 41 first causes the rod 51 to below- 7 cred somewhat, the member 50 being a sufiicient CllfltftllCBHbOVG the stop bar 48 to allow of a movement of the rod51 sufficientto act'uate the presser, and cause the coin to be pushed past the roller 46 before thelug 50 engages the bar 48. Also the member 31 is normally DOSltlOIlBCl. a suflicient distance below the'lever 32 to allow of the above stated depression of the levertaking place'without engagingand moving said member The accompanying moveinent of the arm '47} pushes the bar 48 out of the way of the'p'i'n 50, permitting further downward movement ofthe'i'od 51 and thus enablingthe lever to be depressed for the full depth of t-llGSlOt 41*. The arm 31 will then be cnga ged and depressed,causing the pin 26 to be withdrawn from holding engagement with the sleeve/24' as previously described. At the same timethe pin 57 will beadvanced topro-I ect-across-the lever 32- so that the latter will be held depressed. The-apparatus can then be operatedto dispense gasoline from the pump, as previously set forth. As longv as the pin 26is depressed and held from upward movement by the sleeve 35,the rod 30 cannot move up to its normal position, and conse-' quently the stop 57 will be held'acrossthe path ofthe-lever32; The latter will. then re main depressed untilthe rod. 30 released out. of? slot 41 once he has deposited a 1 coin, and shiftingsaid lever around so that- "another stop .16, controlled by such lever movement, could be moved to be engaged by thestop .17 If'this manipulation oft-lie lever were possible itwould allow a greater move- .witlrthe declutohing action at the-termina :tion of efiCllfillSPGIlSlIlg operation. Y Th sprevents any person from'ii'ioviiigtlie lever 32 merit 0f the rack and consequently a greater amount of gasolineto be dispensed than had been paid for, as will be evident..

Once the-pin 26 returns to its normal position the rod 30 also moves up, withdrawing the pin -57 from above the lever. This lpermits the spring pressed rod 51 topushthe lever upfto its normal positiom'such movemerit of the rod also restoring the presserto itsoriginal position. The parts are then all intheir normalor inoperative positions, enabl ng the lever 32 to be again rotated to sea lect the amountof gasoline to be dispensed.

an d ready1for the receptionfof a coin whose Valuer-correspond to such selected amount.

7 It will be noted that although the lever can be freely rotated at any time, even after a coin is inserted in any slot andbefore the lever is actually depressed, such depression, sufficient to engage the member 31 and lower the member 30, can only take place if the lever I is (lGPlGSSCCl in a slot 41 corresponding to the C0111 chute in. which a 00111 has been depos1ted.

This is because unless such coin is in plat the arm ll will not be actuated to shift the bar as out of the way of the stop 50, and consequently the lever cannot be depressed sufliciently to engage and lower the arm 31.

Each coin chute has its own control mechanism as above described, except that only one arm 31, and only one member are employed. The arm 31 has a plurality of arcuately spaced lugs 31 corresponding in number and spac-j ing to the coin chutes and lever slots, and the member 30 hasa plurality of arms radiating therefrom to actuate the different lever steps 57. A circular band 59, concentric with the casing, is preferably attached to the lever obvious that it may be used also fordispensing lubricating oils and other liquids if so Til desired. c v 7 From the foregoing description it will be readily seen that we have produced such a device as substantially fulfills the objects of the invention as set forth he 'ein.
